Before Abdelrahmanahmed Sallam allegedly killed Cynthia Gregory, police say he used the same gun to scare a teen he met online through Facebook Marketplace.

McKinney police said two teens have been arrested in connection with the fatal shooting of a 19-year-old. Police responded to a shooting call at about 4 a.m. Wednesday to a residence in the 2500 block of Collin McKinney Parkway. They found Vicente Segoviano suffering from a gunshot wound to the chest.

Police arrested a man on Wednesday shortly after they discovered another man shot to death in a Vancouver park. Machou M. Machou, 23, faces possible charges of second-degree murder in the shooting death of a 21-year-old at Jaggy Road Park around 4:24 p.m., the Vancouver Police Department said in a statement.

Police in Little Rock confirmed the deadly shooting in the Park Plaza Mall parking lot is also being investigated as an attempted robbery.

Community activist group Arkansas Stop the Violence held a news conference Thursday to address multiple deadly shootings that took place in Little Rock this week.

The woman shot dead in the parking lot of Park Plaza Monday evening worked as a fundraiser for the Baptist Health Foundation, colleagues said.
